Is stainless better than aluminized steel?
Is stainless better than aluminized steel?
Thanks for the info, I should have figured stainless would last longer, I would hope it wouldn't rust either because I would want to be able to take these off and on.
All the rear O2 sensors do is make sure the cats are doing their job. The real purpose of the tune though, in my opinion anyway, is to take advantage of the freer flowing exhaust. Not as good as long tubes but better then having the cats in place.
